Assume that you have a cylinder with a movable piston. What would happen to the gas pressure inside the cylinder if you do the following?
(a) Decrease the volume to one third the original volume while holding the temperature constant.
increase the pressure by 3 times
double the pressure
decrease the pressure by 1/3
remain the same
(b) Reduce the Kelvin temperature to half its original value while holding the volume constant.
increase by 2 times increase by 4 times
decrease by two times
decrease by four times
remain the same
(c) Reduce the amount of gas to half while keeping the volume and temperature constant.
increase by 2 times decrease by 2 times
decrease by 4 times
remain the same
